Learning how to build a ported subwoofer box properly can lead to a great sub system. While a ported subwoofer box is not as easy to make as a sealed subwoofer box, it can allow for even better sound. This is because it is more efficient, since sound waves from the front and read of the driver are used. Greater volume and deeper bass can be achieved using this type. Follow these steps to learn about how to build a ported subwoofer box.
What you will need to build a ported subwoofer box:
- Port tube
- Wood glue
- Silicone caulk
- Terminal cup
- Buy the necessary equipment, specifically the speaker driver. This is important, because the size of the sub box depends on the driver diameter.
- Determine the dimensions for the ported subwoofer box, following closely to the ideal dimensions for sub box volume. You will need to know a bit of algebra for this step, since most sub boxes are irregularly shaped with some sloped edges.
- Make the designs for your sub box. Cut the box panels out of MDF with a saw.
- Cut openings on two of the panels for the port tube and the other for the terminal cup. Install the terminal cub to the panel using wood screws and glue.
- Install the subwoofer driver on the panel that you made the opening for it. Use wood screws and glue. Attach speaker wire from the driver to the terminal cup connections.
- Assemble the ported subwoofer box panels. Use wood glue and wood screws about every six inches along the edges.
